4 Claims.

My invention relates to improvements in guards for the walls of sinks, particularly, though not exclusively, for partition walls in multi-compartment sinks of the type commonly employed in kitchens.

An object of the invention is to supply a simple, durable and inexpensive guard adapted to be readily applied, as for example, to the partition wall of a sink, to provide a buffer for protecting glasses and dishes against being chipped or broken upon impact against the partition wall as they are passed from one compartment of the sink to another.

A further object of the invention is to provide a guard of the nature above indicated constructed to straddle the upper portion of a sink wall and having longitudinal marginal portions adapted to overlie opposite side portions of such wall, an additional object of the invention being to supply such a structure with means for keeping it in place on a sink wall.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

In the drawing:

Fig. 1 is a perspective view of a double compartment sink showing a guard in embodiment of my invention applied to the partition wall between the two compartments of the sink.

Fig. 2 is a side elevational view of a guard constructed in accordance with my invention.

Fig. 3 is an enlarged detail sectional view taken as on the line 3-3 of Fig. 2. Y

Fig. 4 is a detail sectional view taken as on the line 4 4 of Fig. 3.

Reference being had to the drawing, it will be understood that the invention in guards, as shown, comprises a buffer consisting of an elongated pad A which, in transverse cross-section, is of inverted U-shape so proportioned relative to the partition wall I of the sink II that it is adapted to straddle such partition wall with the intermediate longitudinal portion I2 of the pad A riding the ridge of the partition wall I0 and the depending longitudinal marginal portions I3, I3 of said pad overlying opposite sides of said partition wall.

The pad A consists of two sheets of resilient material, preferably rubber, there being an inner sheet a and an outer sheet a1 superimposed upon said inner sheet a. Placed between the inner and outer sheets of rubber a, a1 at intervals along the pad longitudinally thereof are a plurality of spring clips b which, in shape, conform 2 with that of the inverted U-shape of the pad A proper, each clip having leg portions i4 and an intermediate connecting portion I5 between said leg portions. These clips b, preferably, are of ribbon-like spring steel and they lie atwise between the inner and outer sheets of rubber-a, a1, extending transversely of the pad A with 'the intermediate portion I5 of each clip traversing the longitudinal medial portion I2 of said pad and the leg portions I4 of each clip traversing the longitudinal marginal portions I3 of the pad, the tips of the leg portions I4 of said clips b falling slightly short of the longitudinal edges of said sheets a, a1, as best seen in Fig. 3.

The sheets of rubber a, al will be vulcanized together, preferably as between the members of a molding die in which the inn-er wall of the female die member will be smooth and the outer wall of the mating male die member will be formed transversely thereof with'grooves to accommodate the spring clips b and the material of the inner sheet of rubber a overlying the inner sides of said clips.

The molding of the sheets of rubber a, a1 together and about the spring clips b in such a mold will result in the formation of ribs I6 of rubber along the inner face of the pad A, transversely thereof at the localities of the clipsb.

Normally, in unexed condition, the leg portions I4 of each spring clip b will converge downwardly toward each other so that in saddling the pad A on a sink-wall said leg portions I4 of said spring clips b will be sprung outwardly, all of said clips thereupon acting together yieldingly to grip the longitudinal marginal portions I3, I3 of the pad A against opposite sides of the sink wall, thereby keeping the pad A down in place seated upon said sink-wall.

Aside from the action of the spring clips Znl in causing the pad A to grip the sink-wall Ill and cling in place thereon, said clips b function as stays to prevent the creeping of the pad A from one side to the other of the sink wall upon which it is saddled and, in this respect, said clips b need not be of spring material.

The inner faces of the internal ribs I5 of the pad A bear against a sink-wall and constitute the entire area of contact between the pad and such wall. Accordingly, those portions of the rubber sheets a, a1 spanning the space between said ribs b bridge said spaces and, in addition to the resiliency of the rubber itself, serve to cushion the impact of any glass or dish impinged against the same.

The present guard preferably will be manufactured in a single standard length suited to sink-walls of maximum length, it being contemplated that in any case wherein the pad A is too long for the particular sink-wall to be tted, an end portion of said pad will be appropriately severed therefrom, as by shears or otherwise, along a line of severance between adjacent clips b.

Changes in the speciiie form of the invention, as herein` described, may be made Within the scope of whatk is claimed without departing from the spirit' of tlie invention.

Having described the invention, what zis claimed as new and desired to be protected by Letters Patent is:

1. A guard for sink-Walls comprising an clongated buifer of inverted U-shape in transverse cross section adapted to straddletne walled a sink,I said buifer consisting of a pad of resilient material having channel-dening ribs with bear--v ing faces outstanding from the inner face of the pad; the ribs extending transversely of the pad across its intermediate and marginal portions, and stiiiening means incorporated within said ribs of said pad stifiening the same theres-long and preventing the pad from creeping from one side to other of the sink-wall.

2. A guard for sink-'walls comprising an elongated buier of inverted Ushape in transverse cross section adapted to' straddle the wall oi a sink; said buffer consisting oi a pad including an inner sheet of rubber and an outer sheet of rubber superimposed thereupon, a plurality of spring clips of ribbon steel disposed at intervals along the pad between said sheets of rubber and extending transversely of said pad across the intermediate and longitudinal marginal portion thereof, said sheets of rubber being molded together and about said clips forming channeldening ribs each thereof being coextensive with its respective clip and having a continuous bearing, face outstanding froin the inner face of the pad; said clips acting in concert yieldingly to urge the said bearing faces of said ribs at the said marginal portions of said pa'd into gripping contact with opposite Sides of the sinklw'alL 3; A guard for slnkvvalls comprising an elongated buffer of inverted U-'sliape in transverse cross section adapted to straddle the wall of a sink, said buffer consisting of a pad of resilient material and a plurality of spring clips disposed at intervals along the pad and extending transversely thereof across the intermediate and longi tudinal marginal portions of said pad, the mate? rial of said pad being formed about said clips providing channel-defining ribs, each thereof being coextensive with its respectivey clipl and having a continuous bearing face dutstanding from the inner face of the' pad, said clips' acting in concert yieldingly to urge the said bearing faces of said ribs at the marginal portions of said pad into gripping contact with opposite sides of the sink-Wall. A

4.- d gird for sink-Walls comprising an elongated buffer ofinverted U-shape in transverse cross section adapted to straddle the Wall of a sink,- said buffer consisting of a pad including an inner sheet of rubber and an outer sheet of rubber superimposed thereupon; and a plurality of stay strips disposed at intervals along the pad between said'sheets of rubber and extend-ing transversely of the pad across the intermediate and longitudinal marginal portions thereof; said sheets of rubber being molded together and about said stay strips forming ribs coextensively of the stay strips having faces outstanding from the inner face of the' pad, said ribs dening chan-Y nels in the pad, said faces of said ribs providing bearing surfaces for the' pad between said chan-1 nels, and said strips stiiening said pad and preventing it from creeping from one side to the other of said sink-wall;
